All males have a cremaster muscle (a thin pouch-like muscle in which a testicle rests). When the cremaster muscle contracts (tightens), it pulls the testicle upward toward the body; this is known as the cremasteric reflex. The cremasteric reflex is brought on by such things as cold, touch, and anxiety.
They also appear to change shape and size as the scotum reacts to pull them up into the body and to let them hang low again. There's more on how this works below. When the penis is aroused this also has the effect of making the balls a bit tighter. It's thought that this is to do with the cremaster muscle (see below).
Untucking Your Testicles
If you're new to untucking, try laying on your back or performing a deep breathing exercise to loosen up the muscles around your inguinal canals. Your testicles might lower on their own once the tension is gone. Try a hot shower or bath to help you relax.
Most men's testicles are about the same size, but it's common for one to be slightly bigger than the other. It's also common for one testicle to hang lower than the other. The testicles should feel smooth, without any lumps or bumps, and firm but not hard.
Lax scrotal skin allows your balls to hang lower, away from your body, when your internal temperature rises, like after the gym. When you're in a cold room, testicles shrink up closer to your body for warmth. With age, skin loses collagen. This causes the dermis to become thin and stretchy.

When you climax, it's normal for testicles to "ride up" into your body. In some males, an "overactive" cremaster muscle pulls one (or both) of the testicles all the way out of the scrotum up into the groin. This condition, called retractile testicle, may explain your experience.
If you're suffering from low testosterone levels, you will likely notice a significant reduction in testicular size. You may also notice that your scrotum feels softer than usual.
Calcifications: These are small structures in the testicle or along the main sperm pipeline (vas) can become hard, almost rock like. These are always painless and rarely need to be removed.
When the cremaster muscle contracts, it pulls the testicle up toward the body. The cremaster reflex can be stimulated by rubbing a nerve on the inner thigh and by emotion, such as fear and laughter. The cremaster is also activated by a cold environment.
Genetics might play a role in having dry skin, but other external factors include weather changes, over-washing or scrubbing, allergies, and irritation. Just like any other body part, the skin on your balls can become dry and irritated, particularly if you're prone to dry skin to begin with.
In the 1960′s, Masters and Johnson observed that the testicles elevate just before ejaculation and actually make direct contact with the body. They found that in about 85% of men the right testicle rises before the left one.
Complications of delayed ejaculation can include: Diminished sexual pleasure for you and your partner. Stress or anxiety about sexual performance. Marital or relationship problems due to an unsatisfactory sex life.

You can't always tell when pre-ejaculate (AKA pre-cum) comes out of your penis. You may be able to feel a little wetness on the tip of your penis when it comes out, but you may not notice if you're having sex and other things around your penis are wet, too.
Symptoms that highly suggest low testosterone in adults assigned male at birth include: Reduced sex drive. Erectile dysfunction. Loss of armpit and pubic hair.
There is no specific frequency with which a man should ejaculate. There is no solid evidence that failure to ejaculate causes health problems. However, ejaculating frequently can reduce the man's risk of getting prostate cancer. Ejacu-lation can be through having sex or masturbating a few times a day.
Some studies suggest that moderate ejaculation (2–4 times per week) is associated with a lower prostate cancer risk. However, ejaculating more often doesn't mean your cancer risk drops even more.
While there is no definite age at which male ejaculation ceases, it has been suggested that it may happen when a man reaches his late 40s or early 50s. It is important to note, however, that this is not a universal rule and some men may continue to ejaculate at a later age.
However, if it is released into the open, it cannot live for more than a few minutes. If sperm is not ejaculated, it stays in the man's body for about 74 days. After this, the sperm cells die and are reabsorbed by the body.
If your scrotum looks or feels like it's full of fluid on one or both sides, you may have a hydrocele. A hydrocele may be caused by inflammation or injury but it's not usually painful.
A blow to the testicles may result in pain, bruising, and swelling. In more severe cases, testicular trauma may cause a rupture, potentially leading to a hematocele, which is an accumulation of blood in the scrotal sac.
